Notes. The data were modeled with an absorbed power law model (a), a power law absorbed by Galactic cold matter plus a layer of partially absorbing neutral material (b), and a power law plus two Gaussian lines (representing the iron K$\alpha $ and the OVIII Ly$\alpha $ emission lines)s absorbed by Galactic cold matter and by two layers of partially absorbing neutral material (c). EPIC includes PN, MOS1 and MOS2 data.
